Et lite partikkeleventyr...
Det var en gang for lenge siden da
oljeprisen var høy...
vi hadde forskningsprosjekter og var
ettertraktet
vi deltok på konferanser i fjerne himmelstrøk
vi lekte dronninger og konger og var på
karneval
vi hadde til og med julebord
business was good

..andre tider skulle komme...
.. og oljeprisen falt....
Brikkene begynte å ramle
Kontorer ble tømt
Den 4. revolusjon ristet i oss
Vi var tvunget til omstilling og tenke
veldig veldig hardt og lenge!

Jeg fant jeg fant...
En spredningsmodell vi ikke
hadde brukt på en stund...
Inngangsdata som hadde vokst i
størrelse og som kunne gi nye
muligheter
Noen script og programmer som
hadde blitt forlagt i en skuff..
Kloke hoder, litt hell og lykke

9
Benefits
1. To reduce the environmental footprint from
discharges
2. Comply with regulatory requirements
3. Creation of sustainability targets
Planning phase:
- Use for discharge management
- Use in areas where there are valued ecological resources
- Use when there is particular type of discharges such as TSS
- Use for benchmark measures
Operational phase:
- Use in areas where there are valued ecological resources
- Use when there is planned for mitigating actions if
thresholds are exceeded
Post phase:
- Use in areas where there are valued ecological resources
- Use for documentation purposes
- Use for benchmark measures
